Description

Technical Field

[0001] The invention relates to the technical field of circuit maintenance, and in particular to a power transmission line detection device based on high-stability unmanned aerial vehicle hovering technology. Background Art

[0002] The tension clamp used in power transmission lines provides the tension required for the conductor to be suspended and is a key component that determines the safe operation of the transmission line. During production, the conductor and the tension clamp are pressed into one piece by a hydraulic press. During operation, the tension clamp may cause the conductor to detach from the tension clamp due to poor crimping quality or extremely bad weather, resulting in a transmission line failure. For example, in winter or cold areas, power lines may face the problem of icing. The amount of ice will increase the load on the conductor, causing additional sagging and tension, which will cause the conductor to come out. Therefore, after the tension clamp is made, it is necessary to perform X-ray flaw detection to check whether the internal structure is crimped tightly and firmly. If it is unqualified, it needs to be remade. In addition, the common scene for the prevention and maintenance of tension clamps is the "three-span" line, which refers to the section where the power transmission and distribution line crosses the railway, the first-level and above highways, and the important transmission channel. This line is connected to economic facilities. If a conductor falls off, it is easy to cause significant economic losses and threaten people's lives. Therefore, regular X-ray flaw detection is also required. Traditional manual power line X-ray flaw detection requires personnel to climb the tower.

[0003] The disadvantages of traditional manual X-ray flaw detection of power lines: 1. Power outage required: Currently, X-ray flaw detection is manually operated, and the human body is too close to the wire during operation. In order to ensure that people do not get electric shock, power outages must be performed. Power outage plans are difficult to schedule and coordinate, and the risk of power grid operation is high during power outages. 2. Efficiency and safety: Multiple people are required to climb the tower, and there are safety risks such as falling from heights. The operation time is long, and it is difficult for the ground and tower personnel to communicate in time. Manual tower climbing takes a long time, the operation efficiency is low, and the number of places that can be operated in a day is limited. 3. Complicated operation and high threshold for use: Currently, manual X-ray flaw detection equipment still requires ground personnel to use computers and corresponding programs to operate, and the cost of personnel learning, use and communication is high.

[0004] Therefore, a method of using drones for high-altitude flaw detection is provided. However, when drones are used for high-altitude flaw detection, the drones need to be suspended in the air at all times, which places high demands on the operators. In addition, when the wind is strong, it is difficult for the drones to achieve stable hovering. Summary of the invention
